I wanted to make sure and report back in this forum, the fact that Continuum is now giving away MKL Optimize licenses to all Anaconda users as I mentioned we would . It's not entirely obvious, but to receive the license, you need to get a free account on Anaconda Cloud (anaconda.org). The license will then be downloadable for you at this URL: https://anaconda.org/settings/add-ons. After you download the license, copy it to a directory named ~/.continuum on Linux and Mac or on Windows 7 and above: "C:\Users\<Your User Name>.continuum" (you might have to make that directory first).
